Status Updates From The Vanishing (Fogg Lake #1)

It is getting good. Years ago, the inhabitants of Fogg Lake were subjected to a mysterious gas coming from the nearby cave system, which knocked them all out. Upon awakening, the residents had developed the ability to visualize auras of those around them. Two young women witnessed the murder of a bespeckled man inside those caves. Years later, they became PIs in Seattle. Now they are being hunted.
